Sitting at the north end of the SX set, which is currently in outside storage at Taumarunui.
These coaches were originally built for Queensland Rail, and were built with the provision to be converted into self-propelled electric multiple units, the need for which never came to fruition.
After arriving in New Zealand in the early 2000s, these coaches were modified for commuter services in Auckland. They were traditionally hauled by DBR's 1199 and 1254, with the locomotives running in a top-and-tail formation. DBR 1226 was also painted in MAXX blue colours, but was only used as a back-up.
After being replaced by the AM class electric multiple units in 2014, these coaches are now facing an uncertain future.
One last thing. The way the end of this coach looks - with only one window - reminds me of the Budd M3 units on the Long Island Railroad.
